Just thought i would inform the group, one of my side projects went way faster than expected. Was not supposed to announce this until november.
The 1 angstrom hard coated 854.22nm filter protype is now complete.
Od5 blocked 300 - 1500.
99% transmission on band.
This time it is dual cavity since i got so many complaints about the single cavity 393filter before shipping it.
No more arguing with me please. It solves nothing.
I still need to figure out the actual erf blocking system, so itis not for shipping yet.
I will return with greater news.
Frankenscope? Let's see it!***be advised that NOTHING in this forum has been safety tested and you are reading and using these posts at your own peril. blah, blah, blah... dont mess around with your eyesight when it comes to solar astronomy. Use appropriate filtration at all times...
